Lately my iBook G4 wit Tiger has been getting Kernel panics off and on. I have been trying to solve this problem and have been posting on the apple forms, usenet Newsgroups, and Yahoo Groups. I recently discovered this website and hope it will provide the answer to my problems. Thanks.

I last had a Kernel Panic on July 11, but ever since last week have been getting them left and right. Here is my latest one.

Do you have the discs that came with that Mac? In one of them there is Apple Hardware Test. I would recommend running that - set in looped mode and run a few hours or a whole evening (the howto&faq part of the forum has the instructions for it).
The panics seem caused by hardware - but I would like to see what (if any) errors the hardware test would find. CPU, logic board, other part of hardware, HD, RAM..

Since the panics started (or just before), was anything changed? Was any RAM added? Is all RAM present what Apple shipped with that model? Does there seem to be a pattern for when the panics occur - such as when the Mac is hot, when it's in heavy use, when it's idle, or totally random?
